IK0N we won't see a civil war because just like last time, there are well established procedures for dealing with such things even if we don't have to exercise such procedures very often.
The main point is that each state MUST submit it's electoral votes in accordance with the election laws in place at the time of the election. That means if you don't like the results, you can't go back and change the laws just to make the results different. In another close election, the courts would have to rule based on the results given by the laws in place, just like they did last time.
If people still don't like the results, just like some didn't like the results last time, they have 4 full years to create and pass new election laws to fix any shortcomings in the old election laws.
Anything else is merely illegal tampering with the election process, not grounds for civil war except in the minds of some extreme revisionists who would rather toss the constitution out in any event because it keeps them from forcing their opinions on everyone else. The supreme court was very clear about this last election, and it's why they didn't take too long to return their judgement and opinion, including the minority dissenting opinion. In the end, it's only 4 years until the next election and there still exists an impeachment process in the event of actual presidential misconduct, so the republic marches on as usual.
